Took the 330d MS Touring in for a Sat-Nav check, after one demonstration, they have agreed to put a Case forward.

It went like this, I asked to contact BMW assist from one of their newest cars, with this address {2 Stratford Place, Westfield Stratford City, Montfichet Road, Olympic Park, London E20 1EJ}
to be downloaded by them to the car.
A new 330d M Sport touring was accessed, BMW contacted and duly sent down the address to the Sat Nav, we then asked to navigate to it

it advised 1645 miles to Moscow at least 24 hours continuous driving

The dealer principle was somewhat embarrassed and advised we make our case to BMW uk .
It would appear any E20 post will not work and BMW was sponsoring the Olympics at a E20 post code, how did they get their???????????
